Anyone Else (TMI Maybe)

Has Anyone Else Been Itchy Down There , Went To The doctor and nothing is wrong ? i Have Gotten Tested So Many times For STD's , yeast , BV , once i had BV but i always have this small itch on the inside of my inner Vagina Lip , it itches and bothers me everyday , all day . is it possible i could be allergic to my cats (down there) sounds crazy but my so thinks thats the only other explanation . i'm just annoyed . because theres no blister, cuts, scratches , anything abnormal ,nothing is visably wrong and i have been to numerous doctors and no one says its anything . anyone else have or had this problem ?
